Henry Bluff is a point forming the southwest side of the entrance to Argentina Cove and the north side of the entrance to Las Palmas Cove in Hurd Peninsula, Livingston Island in the South Shetland Islands, Antarctica. The point is dominated by a prominent monilithic formation rising to 163 m and named El Peñón ('The Rock') by personnel of the nearby Spanish Antarctic Base. The area was visited by early 19th century sealers operating from nearby Johnsons Dock.
The feature is named after the American sealing schooner Henry under Captain Benjamin Brunow that visited the South Shetlands in 1820-21.
The point is located at 62°40′30.6″S 60°24′52.1″W which is 1.27 km southwest of Polish Bluff, 1.39 km north-northeast of Salisbury Bluff and 4.96 km south-southeast of Ereby Point (British mapping in 1968, detailed Spanish mapping in 1991, Bulgarian mapping in 1996, 2005 and 2009).
